then it is a thing that Vim can not do, but emacsers easily do; am I right?

There are a *lot* of such things.

vim users generally attempt to construe vim's
smaller feature set *as* a feature, proclaiming
that Emacs is "bloated" and "fat" and "slow", an
example of "creeping featurism", mocking it for
including the proverbial kitchen sink, which, in
their view, is completely unnecessary. Why, they
want to know, is it necessary for a text editor to
come with a module for interfacing with ISO networked
coffee makers? (Answer: because it's possible.)
But there is not really any
question as to which editor is the more featureful;
if featurefulness is your standard for quality, then
Emacs reigns completely supreme. Emacs has text
editing features I miss in OpenOffice, navigation
features I miss in Firefox, and customizeability
out the royal wazootie -- among other things.

The difference is one of viewpoint. The vim users
just want a text editor, pretty much. Emacs users
aren't satisfied with that: they want everything.
vim users see some of Emacs' more excessive features
as "unnecessary" bloat. To the Emacs user, however,
features are desirable even if not strictly necessary.
If every feature had to be justified as strictly
necessary, the Emacs user reasons, why do we even need
computers, when typewriters were working just fine?
The vim user doesn't see things this way; he views
the ability to edit his stuff without retyping it
as necessary, but he views the ability to transparently
edit remote files (accessed via ssh perhaps) in the
same editor as local files as unnecessary; for that
he would just shell out, scp the file, edit it, and
scp the changes back. (Which is basically what tramp
does, behind the scenes; tramp is the Emacs thingydoo
for editing remote files as if they were local.) The
vim user does not consider decoding morse code to be
something he would do in his text editor -- why would
he? The Emacs user, OTOH, knows that, of *course*
Emacs would have the ability to do that. (The command
is called unmorse-region. Assuming you don't have it
bound to a key, you'd access it via M-x.) To the vim
user, playing Zork in a text editor buffer is a
fundamentally preposterous notion -- but Emacs users
have malyon.

"In adjectives, with the addition of inflectional endings, a changeable long vowel (Qamets or Tsere) in an open, propretonic syllable will reduce to Vocal Shewa. This type of change occurs when the open, pretonic syllable of the masculine singular adjective becomes propretonic with the addition of inflectional endings."
